Abstract (en)
[origin: WO2012158499A2] Contemplated lead acid batteries include a monolithic lead/lead alloy composite foil that is preferably formed by cladding mechanically unstressed lead and lead alloy foils. In such batteries, a light-weight non-conductive grid is placed onto the lead alloy side of the composite foil, which is most preferably pre-treated with a lead-containing adhesive that improves retention of the grid and improves retention and intimate electric contact of the positive active material.
